PASTING. MEoHANlslvl.

SPECIFICATION forming part of Letters Patent No. 780,004, dated January 10, 1905.

Original application Bled April ZO, 1903, Serial No. 153,483. Divided and this application filed September 7,1904. Serial To all whom, it Netty concern:

Be it known that I, PETER A. LAWLEss, acitizen of the United States, resid ing at New York city, county of New York, and State of New York, have invented certain new and useful Improvements in Pasting Mechanisms, fully described and represented vin the following specification and the accompanying drawings, forming a part of the same.

This invention relates to mechanism for applying a line of paste or other adhesive material to paper or other material, and this application is a division of an application filed by me on the th day of April, 1903, Serial The invention has been made especially with the idea of providing suitable pasting means for use with a cigarette-machine of that class in which a continuous wrapper-strip is folded about a continuous rod of tobacco and the Vedges ofthe wrapper-strip pasted together to form a continuous cigarette-rod, and the in-Y a continuous-rod-cigarette machine, it will be understood that it is not to be limited to such use.

A full understanding of the invention. can best be given by a detailed description of a preferred construction embodying the various features thereof, and such a description will now be given in connection with the accompanying drawings.

In said drawings, Figure 1 is a planview of a pasting mechanism constructed in accordance with the invention and of the ller forming and wrapping mechanism of the cigarette- Inachine of my original application, Serial No. 153,483. Fig. 2 is a view lookingin the direction of thearrow 2 of Fig. 1. Fig. 3 is a section on line 3 of Fig. 1. Fig. 4 is aview looking in the direction of the arrow 4 of Fig. l.

In the preferred construction shown in the drawings a horizontally-rotating pasting-disk takes paste from a vertically-rotating roll 61, mounted in a suitable paste-receptacle, as 62, and coperatingwith a' grinding-roll 63, which in turn cooperates with another grinding-roll 64, the two rolls 63 and 64 rotating downwardly toward and fromeach other, as indicated by arrows on Fig. 3, and the roll 61 rotating upwardly toward and from the roll' 63. The roll 61 has a concave or circumferentially-grooved periphery to conform to the periphery of the pasting-disk 60, and the roll 63 is formed with a convex periphery corresponding to the grooved roll 61, and the roll 64 has a concave periphery to correspond with the convex periphery of the roll 63. The rolls 63 and 64 are preferably roughened to secure a better grinding action. A doctor-blade 65 is provided for the roll 61 'and is formed with a central notch 66 (shown in Fig. 3 and in dotted lines in Fig. 4) for causing' a circumferential line of paste to be carried by theroll 61, to the pasting-disk 60. This doctor-blade 65 is preferably adjustable, as by being pivotally supported, as shown, and adjusted by means of a screw 67. The edge of the pasting-disk 60 is preferably beveled upward, as shown.

While it may not in all cases be necessary to provide the grinding-roll'64, yet the arrangement shown having the two grindingrolls 63 and 64 in addition to the roll 61 is preferred and forms a feature of the invention. With this construction and with the rolls mounted to rotate vertically and the rolls 63 and 64 preferably rotating downwardly toward and from each other, a very thorough grinding of the paste is secured and all necessity ofgrinding the paste before placing it in the paste-receptacle is avoided. This past-` ing apparatus is especially designed for use with a continuous-rod-cigarette machine and is shown as associated with the wrapping-tube of such. a machine for applying a line of paste to the edge of the wrapper-strip as the latter is advanced through the wrapping-tube. The wrapping-tube shown is the tube described and claimed inmy said original application, Serial No. 153,483, comprising arod or bar 25, having a longitudinal groove 26 and guides for turning the two side edges of the wrapper-strip successively inward and Vdown to( overlap on the tobacco to form the continuous cigarette-rod, and the paste is applied to the last folded side of the wrapper-strip as it passes the pasting-guide 46.

It is desirable to provide means for accurately adjusting the pasting-disk 60 with relation to the wrapping-tube and the edge of the wrapper-strip, and also to provide for rela- `roll 61.

tive adjustment between the pasting-disk and the paste-roll 61. The construction shown provides well for such adjustment. As shown, the paste-fountain 62 and the pasting-disk 60 are carried bya bracket 70, the paste-fountain being secured to av slide 71, mounted on the bracket 7 0 and adjustable thereon toward and away from the pasting-disk, as by means of a screw 72. The pasting-disk is carried by a spindle mounted in screw-bearings 73 and 74, which may beadjusted to elevate or lower the pasting-disk with relation to the paste- The bracket 70 is carried by a Slide 75, supported by a bracket 76 and adjustable thereon, as by a screw 77, to move the pasting apparatus to carry the pasting-disk to-` ward or away from the wrapping-tube and the edge of the wrapping-strip, and the bracket 70 is pivotally mounted at its outer end and may be swung upward or downward to raise or lower the pasting-disk with relation to the wrapping-tube and the edge of the wrappingstrip by means of an adjusting-screw 78 acting against the tension of a spring 79. The paste-fountain 62 is preferably removably secured to the slide 71, as by being held at one Vend by means of an undercut flange 80"and at the other end by means of side holdingscrews 81. By loosening the screws the fountain may thus be readily removed from the slide 71. j

Any suitable means may be provided for driving the pasting-disk and the paste feeding and grinding rolls. As shown, the pasting-disk is driven from av shaft 136 by means of a belt 137, running on pulleys'on the shaft 136 and on the shaft of /the pasting-disk, respectively, and the shafts of the rolls 61, 63, and 64 carry intermeshing gears 140 and are driven by means of a belt running on a pulley on the shaft ofv the roll 64. v

It will be understood that the invention is not to be limited to the exact construction and arrangement of parts as shown for the purpose of illustrating the invention, and to which the foregoing description is mainly confined, but that the invention includes changes and modifications thereof within the claims.

What is claimed is-.

l- The combination of a paste-feeding roll having a longitudinally-concave periphery, a doctor having a notch for securing' a circumferential line of paste on said roll, and a pasting-disk rotating ina plane transverse to the plane of rotation of said roll and mounted to take paste from said roll, substantially as described.
